Cookie,
The next question is seeing that you are based in the UK is: Are you planning to IVA the car?
If you are then you will potentially retrofit any mirrors you actually want after the test. Myself personally have looked for more modern mirrors to go that I can control inside the car. I am just about to start to work out how to wire up some Chrsyler Crossfire mirrors, as I think the they blend well and have the ability to be electrically adjusted, as well as already being E marked so they will pass the test. I don't plan on fitting bullets or Sebrings afterwards.
